2 Channel PWM Frequency Adjustable Square Wave Signal Generator module review

It will not substitute a proper signal generator, but for experimentation with motors, LED's etc. it is perfect. I used to just wire up arduino and put some code in to get PWM out on one of the pins, and used that. But it was inefficient to do it that way. This will save me so much time. Awesome ;)

ICStation said there will be a massive sale happening on Black Friday, so make sure to make use of that and expect a gift as well.

Hello again.I got these yesterday and You CAN get antiphase outputs after all.You connect one lead to output 2 and the other lead to the second hole from the top where the micro usb socket is.Also the output transistors are rated O.2 amps...you can use +ve line and the the pwr output to act as a current sink...as otherwise pwr to ground is limited to 30 milliamps .i just ordered anther 3. the antiphase outputs means i can use it as a beck device and the also a clark zapper too as well as using it as an anti-alzeimer device.

Hello! Many thanks to share this information, I was about to buy the same module but did not had any idea how it works, thanks again.

9:47 The frequency does change in real time, if you hold the up or down button. There is a delay of about 1.5 seconds until it starts to count up/down.
Also, I'm finding that the frequency is up to 5% wrong at frequencies over about 300 Hz.

Are yhe pwm1 and pwm2 in the same phase ? I mean they are both off and on, or one is showing off the other is showing on in a given time.

I had the module connected to my mac through usb to rs232 converter. How can I change the frequency from my mac?

[mihirchauhan]

Can the two outputs be in antiphase? Please reply

[lambojomambari]

Do you have the reference how to use it with arduino? Thanks

[urbanasshole]

Please help with settings.

I want to run both the channel on 50% duty cycle @ 1Khz. While I want to run channel 1 instantaneous, I want channel 2 to commence only after Channel 1 reaches zero duty.

eg: When Ch.1 = 5v, Ch.2 = 0v and vice versa.

Thanks

Should be great for adjusting the speed of fans with PWM input. These are fans typically with 4 wires (power, gnd, tach and PWM).

Did two outputs sinhronized between them?

[esecallum]

I don't understand why they went with a LED display when they could have gone with LCD display with more digits.lower supply consumption.

Hi, can You tell how to control the module using the serial Port?

[tehvisivasankerinarayanan]

can I set 2 different frequency for the PWM 1 and PWM 2?

Hello

May i request you and if ever it is possible for you to demonstrate how to use this pulse generator with stepper motor microstep drive.

Thank you.

Hi, can this module be used to manufacture a DC to AC inverter? Thank you

[lambojomambari]

Can the who output be controlled to send frequency in different occasion (not simultaniously)?

[ericmurphy]

Has anyone figured out how to communicate with these boards with the serial port on the Arduino? I'm having a b*tch of a time attempting to get any of the settings to change via serial port. Any suggestions? Code would be appreciated.

the micro controller under the display is-- 8S003F3P6 google it for info.
i removed the led display by cutting one pin at a time to see if i could disable it but a number of segments always stayed on ..

Interesting but I want to use it on a scan radio..whats the output voltage on the square wave? I really dont want to fry my ic 😓
